摘要
The pion electric polarizability, alpha(E)(pi)+/-, the leading order hadronic contribution to the muon anomalous magnetic moment, alpha(hvp(l))(mu), and the ratio of the V-A and V+A correlators are found within the inA stanton model of QCD vacuum. The results are compared with phenomenological estimates of these quantities from the ALEPH and OPAL data on vector and axial-vector spectral densities.
